Re: [PATCH v2 05/13] drm/sun4i: hdmi: create a regmap for later use

The HDMI driver is written with readl/writel I/O to the registers. However, to support the A31 variant, which has a different layout for the DDC registers, it was recommended to use regfields to have a cleaner implementation. To use regfields, we need to create an underlying regmap.

This patch only adds the regmap. It does not convert the existing driver accesses to use regmap.
